"Maybe I'll suck you off again today, Craig," she said to him, holding his eyes with her own."I'll be looking forward to it." He stood up and kissed h...s sister, then walked over to Charlotte. He whisked off the towel she wore with one quick yank and grinned. "You look better this way." He squeezed one of her firm, pliant tits and planted a kiss on her cheek. "Keep it hot and wet. I'll be back in a few minutes. I need a shower."After Craig left, Charlotte looked to Felicia. "I don't believe how. I told her I could do anything for her so she looked at me. She asked “Anything?” with a sly smile. I said yes anything. So she said get naked.I was surprised by that and thought she was messing. But she wasn’t , she took a belt from my closet and told me she’d whip me if I didn’t. So I got naked and all this kinda turned me on. I had a semi erection and I was scared also. She tied my hand with the belt and took me to the room. There she took another belt and tied my legs. She then took a rope. At first I ignored them but then it started raining hard. She rose from her sleep. After 5 minutes of heavy rain we both were completely drenched and my house was still a few hundred steps away. I looked at her drenched in my arms. Suddenly my eyes fixed on her T shirt and I was awestruck on seeing her beautiful nipples peeping through her wet T shirt. Without a bra on, now it really did not matter if she had worn a T shirt or not because, one could see all through it now, it had turned. As I felt it coming, I fucked her as if my life depended on it. I fucked her hard with all of my strength and then it hit me.I instantly removed my cock from her burning pussy and released my sperms on her belly. The amount was a lot. I fell on her, she welcomed me by wrapping her arms and legs around me. We were breathing hard.While coming down from our animalistic passion, our lips sought each others and we kissed very hard and long, until we regained our senses. Then we looked at each other.
